Abstract
La formation de facettes à l'interface de précipités et matrices est étudié et illustrée pour plusieurs alliages observées par MET. La symétrie crystalline et les contraintes élastiques de la matrice sont démontrées être un facteur important dans le développement de la morphologie et de la structure de l'interface.
Abstract
The role of faceting in the formation of interface structures between a precipitate and its matrix is considered and illustrated with TEM observations on a number of different alloy systems. Crystal symmetry and elastic constraints from the solid matrix are shown to be important factors in the development of morphologies and interfacial structures.
